The National Football League features athletes of diverse sizes and builds. Within the running back position, a spectrum of physiques exists, ranging from powerfully built individuals to those characterized by a lighter frame. This refers to the athlete occupying the position who possesses the lowest weight measurement among all active running backs in the league. For example, if Player A weighs 175 pounds and all other active running backs weigh more, Player A would then be considered this.
Maintaining a lower body weight can potentially offer advantages, such as increased agility, acceleration, and the ability to navigate through smaller openings within the offensive line. Historically, smaller running backs have demonstrated success through elusiveness and receiving abilities. However, reduced mass can also present challenges, potentially increasing susceptibility to injury and limiting effectiveness in short-yardage situations requiring brute force.
